Looking for some advice, I have the retractable side steps on my 2011 VSE. They were not working when I bought the car, the button in the headlining doesn't light up, the fuse in the fuse box for them is ok. I just went for a drive and for some unknown reason the passenger side one extended a little and then stopped.

I have sprayed them with penetrating oil and left then to soak. Is there any way using the iid tool to check them/reset them, any advice would be much appreciated. Current

Could be the ECU that's at fault. It should be under the passenger side fusebox on that model car. Easy to get to and get out, just unplug the plugs and take it out. They are cheap enough on eBay, just make sure the part numbers match as they are different ECU's for pre 2010 steps.
Hope this helps.

I’ve had a nightmare with mine where the button didn’t light up.

In the end I got to the point of giving up on them.

I bought a new ECU to test mine and it turned out not to make a difference. If you’re interested in it then let me know.

So went to have the car checked by Matt 4x4 today they took off the side steps to put the car on the lift, they had a bit of a look, they managed to get them to deploy by putting them in service mode, however as soon as they came out they went back in. They think a terrain response warning is stopping them deploy so possibly not the ecu as we had thought. They did say they are great when they work but are a bit of a night mare! Current

That's interesting.

Do you know how they came to that conclusion? Are you getting fault codes logged from your Terrain Response system? 2002 4.6 Vogue SE - Alveston Red with Lightstone Leather

Yes the terrain response was throwing an error, need to look into this a bit more as wasn't coming up on the Gap but was showing on their diagnostic. Will be doing some more digging and will update you was good to see them working and that they were not siezed!!! Current

Do you mean the DSC button?

If so, that’s a good result.

No, not the dsc button the deployable side step button. I haven't been able to find any issues with my terrain response since the specialist said it was throwing an error, only issue I have now is the steering column longitudinal sensor. Current
